Yes, however it will change the flavor in the sauce.
Tinned coconut milk
Yes anything with dairy in it should be refrigerated.
beat egg whites with a little sugar until very stiff.This is not a non-dairy whipped topping. This is called a Meringue topping minus the Cream of Tarter which keeps the product stiff. You can bake a Meringue.To make a non-dairy creamer you can do a few things. You can try using a Coconut Cream, the top of the Coconut Milk that is thick like milk creamer. You take the Coconut Cream and sugar and you would whip it like you would a Dairy Creamer.I have seen where a non-dairy creamer was used. Prob soy would work. Here is a link I found:http://imaginativeworlds.com/forum/showthread.php?22880-Make-Whipped-Topping-from-Non-Dairy-CreamerHere is another that is truly Vegan:http://www.ivu.org/recipes/holiday/cashew-whipped-j.htmlHere is another option that I found:From a Vegan Cooking Community1. If you're making your own, try a whipped cream recipe replacing the dairy cream with coconut cream. (skim the top from cans of whole fat coconut milk) Real, high-fat, coconut cream. Not the coconut milk + carbohydrate gums stuff you'll sometimes find labeled coconut cream.2. I had a friend who had one of those semi-expensive whipped cream maker things that they use in coffee houses. It has those little nitrous cartridges. She used it to make me soy whipped cream for my coffee one morning. I don't know what she did to make it, but maybe you can look into one of those things.3. MAKES 2 CUPS DAIRY-FREENut creams are easy to make and easily transform a simple dessert into an elegant one by layering it with pudding, as we did in Sweet Potato Parfait. Cashews or walnuts may be substituted for the pecans. PREHEAT OVEN to 350 F. Place pecans in baking dish and toast 10 minutes. Transfer nuts to a food processor and grind to a paste. Add remaining ingredients and process until smooth and creamy.Measure Ingredient2 cup Pecans½ cup Soy milk¼ cup Rice syrup2 teaspoon Vanilla extracthttp://olyblog.net/nondairy-whipped-topping-ideasThese are truly non-dairy options. The other is not a non-dairy option but a Meringue which is somewhat of a different type of whipped topping. These options are closer to what you are looking for.
trans fat
fats from beef, pork, chicken, coconut oil, palm oil, dairy products, cheese, butter, cream and eggyolk.
Since its cream and cream is dairy i would say yes
Dairy / alternatives
Dairy, because ice cream is a milk product
No. Eggs cannot be substituted for dairy products in a recipe. You would get completely different results.
No. Cool Whip is a non-dairy substitute for whipped cream, which is made by (obviously) whipping heavy cream with a whisk or an electric mixer. In general, one can be substituted for the other, but the taste won't be exactly the same.
Dairy Cream (you eat it).
To much :(
